Spores of Alicyclobacillus acidoterrestris can survive during a pasteurization process, after that it can produce off-odor compounds, which cause spoilage of fruit juice and vegetable beverage. In this study, an antibacterial activity of okra (Abelmoschus esculentus) beverage against spores of A. acidoterrestris was investigated with an ultimate purpose to determine whether this can be used in beverage to control the growth of alicyclobacilli in beverage product. The antibacterial activity was assessed via broth dilution assay followed by spread plate technique. Concentrations of okra beverage were ranged from 3.75 to 60 mg/ml. The greatest reduction was observed at 60 mg/ml, which reduced the spore population by 2.34 log CFU/ml. The present study demonstrated that the antibacterial efficacy of okra beverage againsts A. acidoterrestris, which can therefore be considered to have potential to apply in the beverage industry.
